System Board Accessory Board Slots Figure 2-5 Peripheral Component Interconnect Slots The system board contains three 32-bit, 33MHz Peripheral Component Interconnect (PCI) connectors. PCI Slots PCI Slot 1 PCI Slot 2 PCI Slot 3 The PCI slots accept 3.3V and 5V PCI 32-bit 33MHz cards, and Universal PCI cards (which are 3.3V or 5V compatible). Refer to the table on page 30 for the different PCI board installations. The maximum supported power consumption per slot is 25W, either from the 5V or the 3.3V supply. The power consumption must comply with the electrical specifications of the PCI 2.2 specification. Total power consumption for the PCI slots must not exceed 60W. The power consumption of each PCI board is automatically reported to the system through the two presence-detect pins on each PCI slot. These pins code the following cases: • 7W maximum PCI board in the PCI slot • 15W maximum PCI board in the PCI slot • 25W maximum PCI board in the PCI slot The following table shows the various PCI board installations for the different PCI slots: PCI Card 3.3V and 5V Universal (3.3V or 5V compatible) PCI Slot 32-bit/ 33MHz 64-bit/ 33MHz 32-bit/ 33MHz or 66MHz 64-bit/ 33MHz or 66MHz Slots 1, 2, and 3 yes 5V, 32-bit/33MHz yes1 yes yes yes yes2 1. You can install a 64-bit card in a 32-bit slot. However, this card will only operate in 32-bit mode. 2. You can install a 66Mhz card in a 33MHz slot. However, this card will only operate in 33MHz mode. 30 Chapter 2
